DESCRIPTION Field of the Invention

This invention relates to methods and uses involving lipid levels to predict and prevent severe cardiovascular disease-associated fatal complications. The invention thus provides a means to identify and treat high-risk coronary artery disease patients. The methods include analyzing lipid levels of a biological sample, and comparing it to a control.

Background of the Invention

Worldwide, cardiovascular diseases (CVD) are among the leading causes of mortality and morbidity with ever-increasing prevalence. CVD is used to classify numerous conditions that affect the heart, heart valves, blood, and vasculature of the body. One of these conditions is coronary artery disease (CAD). Early targeted initiation of preventive measures of CVD-related fatal complications, such as acute myocardial infarction (AMI) and death, would be of great benefit and can provide a major opportunity in reducing mortality and morbidity in patients suffering from CVD. To this end, accurate identification of individuals who are at risk of developing CVD complications is essential. However, traditional risk assessment fails to recognize a substantial proportion of patients at high risk while a large proportion of individuals are classified as having intermediate risk, leaving patient management uncertain. Additional strategies to further refine risk assessment of high-risk CVD are therefore highly needed. To this end, the inventors have evaluated the role of novel lipidomic biomarkers as a prognostic tool for fatal cardiovascular events in CVD patients.

Plasma or serum total cholesterol, LDL-cholesterol or HDL-cholesterol concentrations have been used as gold standard biomarkers for CVD/CAD risk prediction. However, a number of coronary artery disease (CAD) or acute myocardial infarction (AMI) patients have LDL-C levels within the recommended range suggesting the need for additional diagnostic measures of the residual risk. It is evident from earlier large scale population studies that these measurements associate with the CAD risk and CAD endpoints such as AMI or cardiovascular death. Therefore, preventive treatment strategies have so far been addressed to lower LDL-C concentrations (mainly by statin treatment) and more recently also attempts to raise HDL-C have been made (e.g., by CETP-inhibitors). On the other hand, it has also been observed that one half of the AMI patients actually do have normal LDL cholesterol levels and that there is a substantial residual risk in statin treated patients despite a LDL-C lowering. Furthermore, recent publications have demonstrated that plasma levels of apolipoprotein B (apoB), the main surface protein on LDL particles, and LDL-C, the amount of cholesterol in those particles, are correlated and, considered separately, as positive risk factors. Plasma levels of apolipoprotein A₁, the main surface protein on HDL particles, and HDL-C, the amount of cholesterol in those particles, are also correlated with each other and, considered separately, as negative risk factors. Importantly, for a given usual apoB, lower LDL-C has been observed to associate with a higher risk of AMI supporting the view that, on average, LDL particles with low cholesterol content per particle (small, dense LDL particles) are particularly hazardous. Thus, it seems possible that LDL-C associates directly with the more dangerous molecules carried by LDL-particle and that LDL-C is only an indirect measurement of the risk. Therefore, it is of importance to search for molecules e.g., certain lipid species that are directly related with hazardous (i.e., fatal) cardiovascular events.

Lipid metabolite imbalance is a probable cause of dyslipidemia and the ensuing atherosclerosis manifested in its gravest form as the vulnerable atherosclerotic plaque. Atherosclerotic plaques are complex molecular formations that contain numerous lipids. However, there are other factors than lipid rich plaques or LDL cholesterol that make lipids an attractive group of molecules for CVD studies. Lipids are tightly regulated which makes Lipidomic data robust and informative on the current state of the studied organism. Also, lipids are one of the culmination points of a biological system, more the true outcome than the predictor. Combining Lipidomic data with appropriate biobanked clinical material presents a good opportunity for biomarker discovery. Moreover, lipidomics can be used as a gauge of efficacy and safety in drug development and evolving theragnostics. Lipidomic biomarkers are prime candidates for true companion diagnostics in the CVD area and present many opportunities for improved translational medicine as well.

The plaque building blocks and lipoprotein components that are thought to traffic lipids to the site of lesion formation can now be resolved with Lipidomic studies correlating lipid structure and composition to function and thereby disease pathogenesis. While the number of lipid mediators in the human body is overwhelming, their identification and quantification is facilitated by the advances in mass spectrometry and lipid biochemistry, which today enable the simultaneous high throughput identification and quantification of hundreds of molecular lipid species in several lipid classes (Ejsing C S, et al: Global analysis of the yeast lipidome by quantitative shotgun mass spectrometry. Proc Natl Acad Sci USA 2009, 106:2136-2141; Stahlman M, et al: High-throughput shotgun lipidomics by quadrupole time-of-flight mass spectrometry. J Chromatogr B Analyt Technol Biomed Life Sci 2009 Hiukka A, et al: ApoCIII-enriched LDL in type 2 diabetes displays altered lipid composition, increased susceptibility for sphingomyelinase, and increased binding to biglycan. Diabetes 2009, 58:2018-2026; Linden D, et al: Liver-directed overexpression of mitochondrial glycerol-3-phosphate acyltransferase results in hepatic steatosis, increased triacylglycerol secretion and reduced fatty acid oxidation. FASEB J 2006, 20:434-443.) collectively referred to as the lipidome. Lipidomic studies identify lipid cellular distribution and describe their biochemical mechanisms, interactions and dynamics. Importantly, lipidomics quantifies the exact chemical composition of lipidomes (Han X, Gross R W: Global analyses of cellular lipidomes directly from crude extracts of biological samples by ESI mass spectrometry: a bridge to lipidomics. J Lipid Res 2003, 44:1071-1079).

Due to both high sensitivity and selectivity of lipidomics, even the smallest sample amounts can be analyzed today. The bulk of the lipid data in the art today presents lipids in a sum composition format, i.e. phosphatidylcholine (PC) 34:1 (Brugger B, et al: Quantitative analysis of biological membrane lipids at the low picomole level by nano-electrospray ionization tandem mass spectrometry. Proc Natl Acad Sci USA 1997, 94:2339-2344) where the molecular lipid and the attached fatty acid tails remain unidentified. The identification of molecular lipid species, e.g., PC 16:0/18:1 (Ekroos K, et al: Charting molecular composition of phosphatidylcholines by fatty acid scanning and ion trap MS3 fragmentation. J Lipid Res 2003, 44:2181-2192) is the main feature of advanced lipidomics, which delivers highly resolved molecular lipid species rather than summed fatty acid information. For example, the information of the type of fatty acids and their positions of attachment to the glycerol backbone making up the particular PC molecule is revealed. There are conventional techniques such as thin-layer chromatography combined with gas chromatography but they not only require considerably larger sample amounts and laborious sample preparation, but they do not deliver the molecular lipid species. Despite multiple mass spectrometry techniques capable of characterizing lipid entities, most of them are still unable to deliver reliable high-quality quantitative data in terms of absolute or close-to absolute concentrations. In the context of the present invention, electrospray ionization mass spectrometry-based lipidomics is the preferred technology and can utilize both shotgun and targeted lipidomics for exhaustive deciphering and precise quantification of molecular lipidomes. The superior quality and specificity of shotgun and targeted lipidomics will meet stringent regulatory standards, such as good laboratory practice guidelines (GLP) when set-up in the proper environment. Using these technologies quantification of up to two thousand molecular lipids is possible even in a high throughput format.

Lipidomics is a tool for differentiating patients based on their molecular lipid profiles. Personalized medicine and diagnostics enabled by lipidomics will facilitate the mission of the right individual receiving the right drug at the right time and dose. Several works employing analytes consisting of lipids, proteins and hydrophilic molecules among many others have been conducted to meet the needs of personalized medicine. Recently, non-hypothesis-driven metabolomic screenings have been used to identify novel CVD biomarkers.

For example, WO2004/038381 discloses a method for metabolomically facilitating the diagnosis of a disease state of a subject, or for predicting whether a subject is predisposed to having a disease state wherein the small molecule profile from a subject is obtained and compared to a standard small molecule profile.

WO2008/148857 discloses a method to assess the risk of cardiovascular disease in a patient (including atherosclerosis) by isolating the HDL fraction and sub-fraction from a blood sample of the patient. The components of the HDL fraction or sub-fraction to be measured were Sphingosine-1-Phosphate (SIP), sphingomyelin (SM) and Apolipoprotein A-I (apoA-1).

WO2008/11943 further discloses markers for detecting coronary artery disease that can indicate a patient at risk of having or developing coronary artery disease. These include “first-choice” molecules which were: C18:3 Cholesterol ester, C32:1 Phosphatidylcholine, Alanine, Lipid (mainly VLDL), Lysine, Hexadecanoic acid, C36:2 Phosphatidylcholine, Formate, C32:2 Phosphatidylcholine, C18:2 (Linoleic Acid), Cholesterol, C 18:2 Lyso-phosphatidylcholine, C36:3 Phosphatidylcholine, C34:4 Phosphatidylcholine and C34:3 Phosphatidylcholine.

Furthermore, US2007/0099242 describes a method to determine if a subject is at risk to develop, or is suffering from cardiovascular disease. The method involves determining a change in the amount of a biomarker in the biological sample or HDL sub-fraction thereof, compared to a control sample, wherein the biomarker is at least one of Apolipoprotein C-IV (“ApoC-IV”), Paraoxonase 1 (“PON-1”), Complement Factor 3 (“C3”), Apolipoprotein A-IV (“ApoA-IV”), Apolipoprotein E (“ApoE”), Apolipoprotein LI (“ApoL1”), Complement Factor C4 (“C4”), Complement Factor C4B1 (“C4B1”), Histone H2A, Apolipoprotein C-II (“ApoC-II”), Apolipoprotein M (“ApoM”), Vitronectin, Haptoglobin-related Protein and Clusterin. The document also discloses a method for detecting the presence of one or more atherosclerotic lesions wherein a change in the amount of a biomarker in the biological sample or HDL sub-fraction thereof is detected, compared to a control sample and wherein the biomarker is selected from PON-1, C3, C4, ApoE, ApoM and C4B1. All biomarkers mentioned in this document are protein or lipoprotein biomarkers.

From previous work it cannot be extrapolated that lipid analysis will yield by default a CVD biomarker predictive to the fatal outcomes associated with CVD/CAD. The present invention identifies biomarkers of high risk CVD by absolute, or close to absolute, quantification of defined molecular lipid species instead of profiling multiple analytes. Importantly, while many of the existing biomarker candidates are composite fingerprints of multiple factors, the lipidomics approach herein shows value already at a level of single species or ratios thereof.

In the present invention herein, lipid biomarker concentrations have been measured and quantified in patients with documented CAD who did not show fatal outcomes during the follow-up period (3 years) and in high-risk CAD patients who died due to cardiovascular events during the follow-up period. This invention thus enables accurate usage of the lipid-based biomarkers to identify high risk CVD/CAD patients. Another layer of accuracy was reached through a careful patient selection since it is important to control for factors which may affect the lipid concentration read-outs. Unlike the previous efforts described above, we used specific targeted platforms on a singular technology set-up to analyze lipid species in particular.

The technology and the way it was applied in the context of the inventive teaching presented herein is set apart from similar efforts in the field inter alia due to the following criteria. In sample preparation, samples are strictly controlled and treated identically to avoid potential artifacts that could arise from improper handling. In connection with the present invention, samples were carefully thawed slowly on ice and directly thereafter subjected to a custom-made automated lipid extraction which possesses currently the highest precision in liquid handling, therefore minimizing potential errors. Furthermore, sample freeze-thaw cycles were strictly controlled since this can dramatically affect the lipid stabilities. The automated lipid extraction is based on the method by Folch and colleagues (Folch J, et al: A simple method for the isolation and purification of total lipids from animal tissues. J Biol Chem 1957, 226(1):497-509) which uses chloroform and methanol. This method is preferred when a wide range, from polar to non-polar, of lipid classes are to be extracted with optimal recoveries thus preventing the loss of lipid species. Lipid class specific non-endogenous lipids, when applicable, were used as internal standards to gain highest precision in identification (minimizing false positives) and quantification of monitored molecular lipid species. In this way absolute or semi-absolute amounts of endogenous molecular lipids were determined with the highest precision that can be achieved with today's technologies. The endogenous lipids and respective standards were monitored at the molecular lipid level. In this way, not only false positive identifications were minimized, but molecular lipids could be precisely determined and quantified. Analysis quality was strictly controlled using a novel quality control system. This was mainly controlled by multiple internal standards (IS), external standards (ES), IS/ES ratios, and instrument control samples. By stringently controlling these components, technical and biological outliers were readily identified and rejected from further analysis. To obtain best precision in sensitivity, selectivity and quantification for each molecular lipid different targeted platforms were used. Some lipids are best analyzed using high performance liquid chromatography (HPLC) or ultra high performance liquid chromatography (UHPLC) combined with mass spectrometry based multiple reaction monitoring (MRM) whereas others are best analyzed by direct infusion in combination with mass spectrometry-based precursor ion scanning and neutral loss scanning techniques.

SUMMARY OF THE INVENTION

The present invention provides novel lipidomic markers for predicting and preventing severe CVD/CAD-associated complications, including AMI and death. These markers thus provide a means to identify and treat high-risk coronary artery disease patients. Specifically, it has been found that the lipid molecules, lipid-lipid ratios and lipid-clinical concentration ratios provided herein, when displaying an increased or decreased level—as the case may be—in samples from CAD patients, are useful lipidomic markers for the methods and uses in accordance with the present invention. These sensitive and specific markers were specifically tested to display superior diagnostic and prognostic value compared to the current clinically-used markers predictive for CVD/CAD outcomes. In fact, the currently available biomarkers such as LDL-C or HDL-C have only very limited or no value in predicting the CVD death risk in CAD patients. The present invention therefore represents a significant advantage to other markers which are currently used to diagnose and/or predict CVD and CVD complications, which include LDL-C, total plasma/serum cholesterol and Apolipoprotein B and A1. Thus, the lipidomic markers provided herein allow better diagnosis of or assessment of the risk to develop major CVD complications such as AMI or CVD death.

In accordance with the present invention, methods are inter alia disclosed herein for determining the risk of a patient to develop CVD complications, determining warning signs of CVD risks, (including death, myocardial infarction (MI), angina pectoris, transischemic attack (TIA) and stroke) in said patient.

Methods according to the invention typically comprise the steps of: a) providing a biological sample from a CAD subject; b) determining a lipid concentration, lipid-lipid ratio, or lipid-clinical concentration ratio or (a) corresponding profile(s) from said sample (i.e., determining information on a lipidomic marker in accordance with the invention); and c) comparing said determined lipid concentration, lipid-lipid ratio, or lipid-clinical concentration ratio or said corresponding profile(s) to the corresponding lipid concentration, lipid-lipid ratio, or lipid-clinical concentration ratio or the corresponding profile(s) in a control.

The control may be a sample from (a) CAD patient(s) with no history of major CVD events. It may also be a sample that represents a combination of samples from a CAD patient population with no history of major CVD events. Alternatively, the control may be a set of data concerning a lipidomic marker in accordance with the present invention, e.g., information on the concentration of (a) lipid(s), lipid-lipid ratio(s), or lipid-clinical concentration ratio(s) in accordance with the present invention in a sample when taken from (a) CAD patient(s) with no history of major CVD events, or in a combination of samples taken from a CAD patient population with no history of major CVD events. Said information, and thus the corresponding set of data, may have been previously determined, calculated or extrapolated, or may have yet to be determined, calculated or extrapolated, or may also be taken from the literature.

As mentioned above, the lipidomic marker to be compared between the subject sample and the control (or control sample) may be one or more of the lipid concentration(s), lipid-lipid ratio(s), or lipid-clinical concentration ratio(s) or combinations thereof, i.e., the corresponding profile(s), as described and claimed herein. In this regard, the control or control sample allows establishment of the lipidomic marker baseline or starting point. In connection with all aspects and embodiments of the invention described and claimed herein, the determination of the lipid concentration(s), the lipid-lipid ratio(s) or the lipid-clinical concentration ratio(s) is typically performed using an assay. Collecting information on a lipidomic marker (i.e., the concentration(s) of (a) lipid(s), lipid-lipid ratio(s), or lipid-clinical concentration ratio(s) or combinations thereof, i.e., corresponding profile(s)) from the sample of a patient and, where appropriate, a corresponding control sample, can be performed with various chemical and high-resolution analytical techniques. Suitable analytical techniques include, but are not limited to, mass spectrometry and nuclear resonance spectroscopy. Any high-resolution technique capable of resolving individual lipids or lipid classes and providing structural information of the same can be used to collect the information on the lipidomic marker in question, e.g., lipid profile from the biological sample. Collecting the information on the lipidomic marker with mass spectrometry (MS) is one of the preferred embodiments of the current invention. The MS instrument can be coupled to a direct sample infusion method, such as a robotic nanoflow ion source device, or to a high performance separation method such as high performance liquid chromatography (HPLC) or ultra performance liquid chromatography (UPLC).

Again in accordance with all aspects and embodiments described and claimed herein, both the sample from the subject and the control sample is preferably a blood sample, more preferably a blood plasma sample, or also preferably a blood serum sample. It may also be a fraction of blood, blood plasma or blood serum, e.g., a lipoprotein fraction. A blood sample can be prepared and plasma or serum, or fractions thereof, can be separated therefrom with techniques well known to the person skilled in the art. Alternatively, both the sample from the subject and the control sample may also be a tissue sample, e.g., artery tissue, such as carotid artery tissue, or artery plaque material, such as carotid artery plaque material.

The lipidomic markers of the present invention allow for prediction and prevention of fatal CVD complications. This will facilitate earlier intervention, less symptom development and suffering and decreased morbidity/mortality associated with CVD. Thus, the lipidomic markers described and claimed herein allow for individual tailoring of drug intervention for patients being at risk to develop major CVD complications.

In other words, the present invention discloses diagnostic and/or predictive lipid markers and lipid-lipid or lipid-clinical concentration ratios for use in predicting CVD complications such as AMI or CVD death. The invention uses the measurement of lipid concentrations, lipid-lipid and/or lipid-clinical concentration ratios to determine the risk of said subject to develop CVD complications such as AMI and/or CVD death. The subject may have previously suffered from a cardiovascular disease event such as angina pectoris, myocardial infarction or stroke. The CVD may or may not be a result of atherosclerosis.

Accordingly, in one aspect of the invention, a method is provided for determining whether a subject is at risk to develop one or more CVD complications, such as AMI or CVD death, said method comprising determining in a sample from said subject the concentration(s) of one or more lipid(s), wherein (an) increased or decreased concentration(s) in said sample, when compared to a control sample, is (are) indicative of said subject having an increased risk of developing one or more CVD complications, such as AMI or CVD death, wherein the one or more lipid(s) whose increase(s) in concentration is (are) compared to the control is (are) selected from (Tables 4a and 7a): Cer(d18:1/18:0), Cer(d18:1/20:0), Cer(d18:1/24:1), GlcCer(d18:1/18:0), LacCer(d18:1/18:0), LacCer(d18:1/20:0), LacCer(d18:1/22:0), LacCer(d18:1/24:0), PC O-32:0 (KDdiA-PC), PS O-16:0/18:2-alkenyl, PS O-16:1/18:2-alkyl, PS O-18:0/18:2-alkenyl (PS O-18:1/18:2-alkyl), PS O-18:2/16:0-alkenyl and Total LacCer; and wherein the one or more lipid(s) whose decrease(s) in concentration is (are) compared to the control is (are) selected from (Tables 4a and 7a):

In the context of the present invention, CVD is typically characterized by coronary artery disease, peripheral artery disease, a stroke and/or CVD death. The CVD in the subject whose sample is analyzed in accordance with the invention may be atherosclerosis-induced. However, the invention also embodies methods involving subjects who are at risk of developing CVD, but who may or may not have atherosclerosis.

In a further embodiment, the methods of the invention may further comprise determining the serum level of total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), Apolipoprotein B (ApoB) and/or Apolipoprotein C-III in the subject's sample. In one embodiment of the invention, the subject does not have elevated serum levels of one or more of total cholesterol, low-density lipoprotein cholesterol (LDL-C), Apolipoprotein C-III or Apolipoprotein B (ApoB), or a decreased serum level of HDL-cholesterol (HDL-C).

As mentioned above, for the purposes of the present invention, a control sample may be obtained from (a) CAD patient(s) or a group of CAD patients that has/have remained free of any major CVD complications e.g., by mixing a variety of samples from said population. If a group of CAD patients is used then several lipid profiles from a population are combined and the lipidomic marker is created from this combination. The levels or amounts of the individual lipids or the lipid-lipid ratios or lipid-clinical concentration ratios in the sample from a subject are compared to the levels or amounts of the lipids or lipid ratios in the control for determining the risk of one or more of CVD complications, such as AMI or CVD death, in said subject.

The invention encompasses the analysis of lipid concentrations, lipid-lipid ratios and/or lipid-clinical concentration ratios in samples from a subject that has been or is being treated with one or more statins and/or any other HMG-CoA reductase inhibitor.

Alternatively, the invention encompasses the analysis of lipid concentrations, lipid-lipid ratios and/or lipid-clinical concentration ratios in samples from a subject that has not yet undergone statin therapy or therapy with any other HMG-CoA reductase inhibitor.

In accordance with the aspects and embodiments of the invention described and claimed herein, the statin may be one selected from the group consisting of atorvastatin, cerivastatin, fluvastatin, fluvastatin XL, lovastatin, pitavastatin, pravastatin, rosuvastatin, and simvastatin.

Collecting information on a lipidomic marker or a lipidomic profile from a subject's biological sample can be performed via various chemical and high resolution analytical techniques. Suitable analytical techniques include but are not limited to mass spectrometry and nuclear resonance spectroscopy. Any high resolution technique capable of resolving individual lipids or lipid classes and providing structural information of the same can be used to collect the lipid profile from the biological sample. For methods of the present invention the level of the lipid is determined by using mass spectrometry, nuclear magnetic resonance spectroscopy, fluorescence spectroscopy or dual polarisation interferometry, a high performance separation method such as HPLC or UPLC and/or an immunoassay such as an ELISA. According to an alternative or further embodiment an analyte in a sample can be detected and/or quantified by combining the analyte with a binding moiety capable of specifically binding the analyte. The binding moiety can include, for example, a member of a ligand-receptor pair, i.e., a pair of molecules capable of having a specific binding interaction. The binding moiety can also include, for example, a member of a specific binding pair, such as antibody-antigen, enzyme-substrate, nucleic acid-based ligands, other protein ligands, or other specific binding pairs known in the art. In a preferred embodiment, the lipidomic profile is collected with mass spectrometry (MS), wherein the MS instrument may be coupled to direct infusion methods and high performance separation methods such as HPLC or HPLC. The amount of the individual lipids or lipid classes in the collected lipidomic profile is used when comparing the collected lipid profile to a control.

The methods of the present invention may be used for determining a risk of said patient to develop CVD complications, particularly severe CVD complications such as death and myocardial infarction (MI), including acute myocardial infarction (AMI).

In one embodiment of the invention, a method for treating or preventing CVD complications, such as AMI or CVD death, in a subject in need thereof is provided. The method comprises administering a therapeutically effective dose of a drug capable of modulating one or more of the lipid concentration(s), lipid-lipid ratio(s) or lipid-clinical concentration ratio(s) described in Tables 4-13, wherein the dose is such that said one or more lipid concentration(s), lipid-lipid ratio(s) or lipid-clinical concentration ratio(s) in a sample of said subject does not significantly change when compared to (a) corresponding lipid concentration(s), (a) corresponding lipid-lipid ratio(s) or (a) corresponding lipid-clinical concentration ratio(s) in a control, e.g., a control sample. In a preferred embodiment, the drug is a statin or another HMG CoA reductase inhibitor. Particularly preferred statins in this regard are atorvastatin, cerivastatin, fluvastatin, fluvastatin XL, lovastatin, pitavastatin, pravastatin, rosuvastatin or simvastatin. In another preferred embodiment, the drug is niacin (nicotinic acid); a cholesterol absorption inhibitor, such as ezetimibe or SCH-48461; a cholesteryl ester transfer protein (CETP) inhibitor, such as torcetrapib, anacetrapib or JTT-705; a bile acids sequestrant, such as colesevelam, cholestyramine and colestipol; or a fibrate, such as fenofibrate, gemfibrozil, clofibrate, and bezafibrate. Alternatively, it may also be a phytosterol.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1.

This FIGURE demonstrates the importance of molecular lipid measurements. Two examples are given in this FIGURE to illustrate that two closely related molecular lipids may have a very different or even opposite effect on CVD complications. First quadrangles are used to indicate two Lactosylceramides (LacCer). LacCer (18:1/20:0) is a significant predictor for CVD Death, while closely related LacCer (18:1/16:0) has only limited or no value as a risk predictor. Second example proves that that two lipid species from the same lipid class may have even an opposite effect on CVD events. PC (18:0/20:4) proved to be a protective lipid against CVD death while PC (16:0/16:0) seems to increase CVD complications.

DETAILED DESCRIPTION OF THE INVENTION Definitions

Coronary vascular disease/cardiovascular disease (CVD) has its general meaning in the art and is used to classify numerous conditions that affect the heart, heart valves, blood, and vasculature of the body, including CAD. In the present invention the terms CVD and CAD may be used interchangeably. Cardiovascular diseases include endothelial dysfunction, coronary artery disease, angina pectoris, myocardial infarction, atherosclerosis, congestive heart failure, hypertension, cerebrovascular disease, stroke, transient ischemic attacks, deep vein thrombosis, peripheral artery disease, cardiomyopathy, arrhythmias, aortic stenosis, and aneurysm. Such diseases frequently involve atherosclerosis. In a preferred embodiment of the invention, the cardiovascular disease is a cardiovascular disease associated with atherosclerosis.

CAD is coronary artery disease, AMI is acute myocardial infarction, ACS is acute coronary syndrome, CAC is coronary artery calcification, RCT is reverse cholesterol transport, LDL is low density lipoprotein, HDL is high density lipoprotein, LDL-C is low density lipoprotein cholesterol, HDL-C is high density lipoprotein cholesterol, ApoA is Apolipoprotein A, ApoB is Apolipoprotein B, ApoC is apolipoprotein C, MS is mass spectrometry, HPLC is high performance liquid chromatography, and UPLC is ultra performance liquid chromatography.

As used herein, “a subject” includes all mammals, including without limitation humans, but also non-human primates, dogs, cats, horses, sheep, goats, cows, rabbits, pigs and rodents.

A “sample” is defined as any biological sample obtained from a subject or a group or population of subjects. For the purposes of the present invention, the biological sample may be whole blood, blood serum, or blood plasma. It may also be a tissue sample. However, a preferred embodiment is wherein the biological sample is plasma or serum. Taking a blood sample of a patient is a part of normal clinical practice. The blood sample can be taken in connection with e.g. measuring the cholesterol levels in the patients. The collected blood sample can be prepared and serum or plasma can be separated with techniques well known to a person skilled in the art. Vena blood samples can be collected from patients using a needle and a BD Vacutainer® Plastic Tubes or Vacutainer® Plus Plastic Tubes (BD Vacutainer® SST′ Tubes contain spray-coated silia and a polymer gel for serum separation). Serum can be separated by centrifugation at 1300 RCF for 10 min at room temperature and stored in small plastic tubes at −80° C.

For the purposes of the present invention, lipids from the Lipidomic analysis were named according to the following nomenclature: CE is cholesteryl ester, Cer is ceramide, DAG is diacylglycerol, PC O is ether-linked PC, GD is disialogangliosides, GlcCer is galactosyl- and glucosylceramides, GM is monosialogangliosides, LacCer is lactosylceramides, LPC is lysophosphatidylcholine, PC is Phosphatidylcholine, PE is Phosphatidylethanolamine, PI is Phosphatidylinositol, SM is Sphingomyelin, S1P is sphingosine-1-phosphate.

The nomenclature X:Y indicates, X number of total carbon atoms in the fatty acid(s) portions of the molecule, and Y the total number of double bonds in the fatty acid portion(s) of the molecule.

The nomenclature AB indicates, for a molecule of DAG and PC, A and B types of fatty acid moieties attached to the glycerol backbone of the molecule.

The nomenclature (dC/A) indicates, for a molecule of Cer, GlcCer, LacCer and SM, C the type of long-chain base with an amide-linked, A, fatty acid moiety.

The wording “compared to a control sample” as used herein will be understood to include embodiments where control samples are actually analyzed in respect of a lipidomic marker of interest, i.e., in respect of the concentration of one or more of the lipid(s), the lipid-lipid ratios, or the lipid-clinical concentration ratios or combinations thereof as specifically described herein in connection with the various aspects and embodiments of the present invention. It will be appreciated, however, that the above wording also includes embodiments where the corresponding information on said lipidomic marker in said control sample is merely taken from the literature, or has been previously determined, calculated or extrapolated, or is yet to be determined, calculated or extrapolated.

As used herein, the term “antibody” includes monoclonal and polyclonal antibodies, whole antibodies, antibody fragments, and antibody sub-fragments that exhibit specific binding to a said lipid. Thus, suitable “antibodies” can be whole immunoglobulins of any class, e.g., IgG, IgM, IgA, IgD, IgE, chimeric antibodies or hybrid antibodies with dual or multiple antigen or epitope specificities, or fragments, e.g., F(ab′)₂, Fab′, Fab and the like, including hybrid fragments, and additionally includes any immunoglobulin or any natural, synthetic or genetically engineered protein that acts like an antibody by binding to a specific antigen to form a complex. The term “antibody” encompasses antigen-binding fragments of antibodies (e.g., single chain antibodies, Fab fragments, F(ab′)₂, a Fd fragment, a Fv fragment and dAb fragments) as well as complete antibodies. For example, Fab molecules can be expressed and assembled in a genetically transformed host like E. coli. A lambda vector system is available thus to express a population of Fab's with a potential diversity equal to or exceeding that of subject generating the predecessor antibody. See Huse W D, et al., Science 1989, 246:1275-81. Such Fab's are included in the definition of “antibody.” The ability of a given molecule, including an antibody fragment or sub-fragment, to act like an antibody and specifically bind to a specific antigen can be determined by binding assays known in the art, for example, using the antigen of interest as the binding partner.

Antibodies against lipids in accordance with the present invention may be prepared by methods well known to those skilled in the art. For example, mice may be immunized with a lipid with adjuvant. Splenocytes are harvested as a pool from the mice that were administered 3 immunizations at 2-week intervals with test bleeds performed on alternate weeks for serum antibody titers. Splenocytes are prepared as 3 aliquots that are either used immediately in fusion experiments or stored in liquid nitrogen for use in future fusions.

Fusion experiments are then performed according to the procedure of Stewart & Fuller, J. Immunol. Methods 1989, 123:45-53. Supernatants from wells with growing hybrids are screened by enzyme-linked immunosorbent assay (ELISA) for monoclonal antibody (MAb) secretors on 96-well ELISA plates coated with the said lipid. ELISA positive cultures are cloned by limiting dilutions, typically resulting in hybridomas established from single colonies after 2 serial cloning experiments.

Materials and Methods

This study is a sub-cohort of the LURIC study that is a large scale prospective study on cardiovascular epidemiology. LURIC database contains clinical information over 3000 patients including baseline coronary angiography, clinically used biomarker data and also e.g. CVD mortality data for the follow-up period (3 years). In this biomarker study the inventors compared CAD cases (n=62) that died during the follow-up due to CVD with patients (n=173) having a stable CAD. Subjects with a significant atherosclerosis level in the angiogram but no CVD related death during the follow-up were used as controls, while the case group had similarly a significant atherosclerosis based on the angiography at baseline and in addition they died during the follow-up due to acute cardiovascular events. A statistical analysis was performed separately also for cases (n=48) and controls (n=124) that were not treated with statins. The clinical characteristics are described in Table 1.

Analytical Methods

Mass Spectrometry Driven Lipidomics

Direct infusion coupled to tandem mass spectrometry, i.e. shotgun lipidomics, and two liquid chromatography tandem mass spectrometry (LC-MS/MS) approaches, i.e. ceramide and cerebroside lipidomics, were used to identify lipid biomarkers for coronary artery disease (CVD) risk by analyzing molecular lipid species in human serum, plasma, and carotid artery plaques. The applied methods were optimized especially for quantification of molecular cholesteryl esters (CE), phosphatidylcholines (PC), lysophosphatidylcholines (LPC) and other lysophospholipids (LPL), ether-linked phosphatidylcholines (PC O) and other ether-linked phospholipids (PL O), phosphatidylserines (PS), phosphatidylethanolamines (PE), phosphatidylglycerols (PG), phosphatidylinositols (PI), phosphatidic acids (PA), diacylglycerols (DAG), ceramides (Cer), glucosylceramides (GlcCer) and lactosylceramides (LacCer).

The following materials were used according to the methods. HPLC or LC-MS grade of chloroform, methanol, water, acetonitrile, formic acid, methanol, isopropanol, ammonium acetate, acetic acid, potassium chloride and butylated hydroxytoluene (BHT) were purchased from Sigma-Aldrich (St. Louis, Mo., USA).

HPLC column (Acquity BEH C18, 2.1×50 mm id. 1.7 μm) was purchased from Waters (Milford, Mass., USA). HPLC pre-column (Widepore C18 4×2.0 mm) was purchased from Phenomenex (Torrance, Calif., USA). All labware used for the extraction were resistant to chloroform. Aerosol resistant filter tips (Molecular BioProducts) and Eppendorf 2 ml safe-lock tubes, 96-well twin.tec PCR plates, and Pierce-it-lite thermo-sealing foils were purchased from VWR International (West Chester, Pa., USA). CO-RE Filter Tips and 96-well 2 ml Whatman Uniplates were purchased from Hamilton Robotics (Bonaduz, Switzerland). Synthetic lipid standards were purchased from Avanti Polar Lipids (Alabaster, Ala., USA) and from Matreya (Pleasant Gap, Pa., USA).

Lipids were extracted in chloroform:methanol according to the following protocols. Samples were spiked with known amounts of non-endogenous synthetic internal standards for data normalization and endogenous lipid quantification. In shotgun lipidomics analysis; LPC 17:0, PC 17:0/17:0, PA 17:0/17:0, PE 17:0/17:0, PG 17:0/17:0, PS 17:0/17:0, DAG 17:0/17:0, D6-CE 18:0, in ceramide and cerebroside lipidomics; Cer d18:1/17:0, D3-LacCer d18:1/16:0, and D3-GlcCer d18:1/16:0, were used as internal standards. Post-extract spiked non-endogenous synthetic external standards were used for quality controlling. Stock solutions of standards were prepared by dissolving appropriately weighed amounts of each standard in chloroform:methanol (2:1, V:V) to achieve a final concentration of 500 μM. An internal standard mixture containing each of the standard stock was created and used in lipid extraction.

Samples and quality control samples for each extraction batch were thawed on ice. The carotid artery plaque samples were weighed on ice by using a cryo-box and homogenized in ice-cold 70% methanol in water. The Mixer Mill 301 Teflon adapters were kept at −20° C. Homogenization was performed at 15-25 Hz for 2-15 minutes with Mixer Mill 301 (Retch GmbH, Germany).

Lipid extraction of human samples was carried out in automated fashion using a Hamilton MICROLAB STAR system (Hamilton Robotics, Switzerland). Well-mixed samples were aliquoted into a 96-well 2 ml Whatman Uniplate containing ice-cold methanol and 0.1% BHT. 5 μl of serum and plasma and 30 μl of carotid artery plaques were used for shotgun- and ceramide and cerebroside lipidomics and 100 μl of serum and plasma. The samples were mixed thoroughly after each step in the extraction protocol. The extraction proceeded at room temperature by adding an appropriate volume of internal standard mixture and chloroform. In shotgun and ceramide and cerebroside lipidomics, the organic phase separation was facilitated by adding 20 mM acetic acid and centrifuging the plate for 5 min at 500×g. The organic phase was transferred into a new 96-well 2 ml Whatman Uniplate. The remaining water-containing phase was washed by adding appropriate volume of chloroform followed by centrifugation. The two organic phases were pooled and evaporated under N₂ until dryness. The lipid extracts were then re-dissolved in chloroform:methanol (1:2, v:v) including the addition of the synthetic external standard.

In shotgun lipidomics, lipid extracts were analyzed on a hybrid triple quadrupole/linear ion trap mass spectrometer (QTRAP 5500, AB Sciex) equipped with a robotic nanoflow ion source (NanoMate HD, Advion Biosciences). The instruments were operated in positive and negative ion modes. In positive ion the spray voltage was set to 1.0 to 1.4 kV and in negative ion mode to −1.0 to −1.4 kV. A gas pressure of 0.3-0.8 psi was used and the interface heater was set at 60° C. The collision energy (CE) and declustering potential (DP) was optimized for each lipid class using synthetic standards. The mass spectrometer was operated in unit resolution mode using a scan speed of 200 Da/s. Molecular lipids were analyzed in both positive and negative ion modes using multiple precursor ion scanning (MPIS) and neutral loss scanning (NLS) as described by Stahlman and colleagues (Stahlman M, et al. High-throughput shotgun lipidomics by quadrupole time-of-flight mass spectrometry. J Chromatogr B Analyt Technol Biomed Life Sci 2009).

In ceramide and cerebroside lipidomics, the high performance liquid chromatography (HPLC) analyses were conducted in the following way. Chromatographic apparatus consisted of a CTC HTC PAL autosampler (CTC Analytics AG, Switzerland), a Rheos Allegro UHPLC pump (Flux Instruments AG, Switzerland), an external column heater set to 60° C. for ceramide and cerebroside lipidomics. The extracted samples, 10 μl of each, were injected into the pre-column followed by the analytical column and delivered to the mass spectrometer at a flow rate of 500 μl/min. In ceramide and cerebroside lipidomics, A gradient was used for lipid analyte separation with solvent A comprising 10 mM ammonium acetate in HPLC grade water containing 0.1% formic acid and solvent B of 10 mM ammonium acetate in acetonitrile:isopropanol (4:3, V:V) containing 0.1% formic acid. The gradient was constructed in the following way: 0 min-65% B; 2 min-65% B; 2.5 min-75% B; 17.5 min-100% B; 22.5 min-100% B; 22.6 min-65% B; 25 min-65% B.

The lipid extracts were analyzed by HPLC-MS/MS. The MS analysis was performed on a hybrid triple quadrupole/linear ion trap mass spectrometer equipped with the Turbo V™ Ion Source (4000 QTRAP, AB Sciex). The instrument was operating in positive and negative ion modes. The ion source voltage was set to 5500V for ceramide and cerebroside lipidomics. The collision energy (CE) and declustering potential (DP) was optimized for each lipid class using synthetic standards. A 20 sec dwell time was applied for each scan.

The data processing was done in the following way. Initially the retention time (in LC mode) and identification of each peak was done using endogenous standards and by Information Dependent Acquisition (IDA) experiments where applicable. The raw data were processed according to peak detected and retention time (in LC mode) in automated fashion. A stringent cutoff was applied for separating background noise from actual lipid peaks. Each sample was controlled and only accepted when fulfilling the stringent acceptance criteria. Peak area counts (cps) of detected peaks were converted into a list of corresponding lipid names. Lipids were normalized to their respective internal standard and sample volume or tissue weight to retrieve their concentrations.

Several quality controls were used in the lipidomic analyses. A calibration line using synthetic or isolated standards was obtained prior to sample analysis. Synthetic standards were chosen based on application and had similar properties to the endogenous lipids or analyte(s) of interest. The calibration line consisted of a minimum of five standards points covering the expected quantification range. A sample extracted without standard and standards extracted with no matrix, were included with the calibration line.

The calibration line was used to determine the dynamic quantification range for each lipid class monitored, e.g., the linear quantification limits. As the internal standards used behave in the same way as endogenous lipids they were used for quantifying endogenous lipid species. The calibration lines were based on the same internal standards that were used for quantification of the endogenous lipids.

In each sample extracted for lipids, the ratio of synthetic internal standards (IS) to corresponding post-extract spiked external standard (ES) was determined. The peak area (cps) ratio of internal to external standard (IS/ES) was used for calculating the Coefficient of Variation (CV) across all samples. The IS/ES ratio enabled the calculation of lipid extraction recovery.

Instrument control (IC) was included at the start, middle and end of each run. IC sample analyzed was an extracted reference plasma sample and a set of standards to monitor the instrument's performance, i.e., the intra- and inter-assay variation.

For each platform, a stringent cutoff was applied for separating background noise from actual lipid peaks. Each sample was controlled and only accepted when fulfilling the stringent acceptance criteria. Masses and counts of detected peaks were converted into a list of corresponding lipid names. Lipids were normalized to their respective internal standard and sample volume to retrieve their concentrations.

Statistical Analyses

Percentage changes in lipid concentrations between control and case groups were calculated as follows: 100*(AVG[C] in case group AVG[C] in control group)/AVG[C] in control group Statistical significance was assigned based on standard t-test p-values.

In addition, ROC curves were used for finding lipid molecules and concentration cutoffs that separate the best cases from controls. Selectivity is calculated as a number of correctly identified cases divided by the total number of cases. Specificity is calculated as a number of correctly identified controls divided by the total number of controls. Selectivity and specificity was calculated for each lipid concentration, lipid to lipid ratio and ratio of lipid to clinical concentrations.

Ethics

The LURIC study was approved by the ethics review committee at the “Landesärztekammer Rheinland-Pfalz” (Mainz, Germany). Written informed consent was obtained from each of the participants.

Results

In this LURIC study sub-cohort, the traditional biomarkers including LDL-cholesterol and HDL-cholesterol concentrations were practically identical in both groups and therefore were not predictive of CVD-related mortality in this study.

Multiple lipidomic markers appeared as significant predictors of CVD death (Tables 4-13). A total of 151 molecular lipids were quantified. The significant predictors were selected based on the top fifty candidates from each category, when available. The biomarker candidates based on molecular lipid concentrations are presented in Tables 4, 7, 10 and 13. The candidates were selected according to the following criteria: t-test p-value ≤0.05 or sensitivity ≥60% and specificity ≥60%. From traditional clinical chemistry only apolipoprotein A1 and total cholesterol reached statistical significance with p-value lower than 0.05, but % change was less than 10% between controls and cases, other clinical values did not show any statistical significance. The predictive value of new lipidomic biomarkers was increased when their levels were expressed as distinct lipid-lipid ratios or lipid-clinical ratios (e.g. LDL-C or HDL-C). The top biomarker candidates are presented in Table 11. Top candidates from each category, when available, were selected based on the following selection criteria: t-test p-value ≤0.05 and sensitivity ≥60% and specificity ≥60%.

Importance of Detailed Molecular Lipid Analyses

Recent evolvement of mass spectrometry driven lipid analysis approaches has made it possible to resolve complex lipidomes to their molecular lipid species level at high-throughput and quality required for analyses of clinical cohorts. As a result of the high sensitivity and selectivity of the methods, a lipidome-wide analysis of minute sample amounts has become feasible. Present technologies are capable of identifying lipids with different sum compositions, i.e. phosphatidylcholine (PC) 34:1, but more important is the identification of molecular lipid species, e.g. PC 16:0/18:1. In the latter analysis, information of the type of fatty acids and their positions attached to the glycerol backbone making up the particular PC molecule is retrieved.

The seminal work of Shinzawa-Itoh and colleagues showed by highly sophisticated experiments that the oxygen transfer mechanism in cytochrome c oxidase requires a specific phosphatidylglycerol molecular lipid with palmitate and vaccenate at the sn-1 and sn-2 positions respectively on the glycerol backbone (Shinzawa-Itoh K, Aoyama H, Muramoto K et al: Structures and physiological roles of 13 integral lipids of bovine heart cytochrome c oxidase. EMBO J 2007, 26:1713-1725). In line with other studies, this undoubtedly indicates that the lipid structure is an essential determinant of the biological effect. Therefore, molecular lipidomics is an essential for biomarker discovery. FIG. 1 illustrates the importance of molecular lipid data by comparing the biomarker value of two PC and LacCer molecules in predicting CVD mortality in the LURIC cohort. The data reveals that while LacCer(d18:1/20:0) is a significant CVD predictor, LacCer (d18:1/18:16:0) has low biomarker potential. In addition, two PC molecules PC (18:0/20:4) and PC (18:0/16:0) have even opposite effects on CVD complications. Thus, it is always necessary to identify and quantify all lipid species for lipid classes of interest including but not limited to cholesterol esters, different phospholipid classes, ceramides, cerebrosides (lactosylceramides, glycosylceramides), and gangliosides.

The biomarker ability of measured lipids was assessed also by calculating the sensitivity and specificity values for each lipid and their ratios to other lipids or classical biomarkers such as LDL-C and apolipoproteins. This ROC curve analysis revealed a number of biomarker candidates that have equal of higher than 60% sensitivity and specificity for predicting CVD complications (Tables 7-9).

The preferred lipid molecules of the invention were selected as follows: a) it was likely to be biologically meaningful, b) it preferably belongs to a family of lipids that are behaving similarly, c) it is expressed in meaningful & measurable concentrations, d) it has very significant p-value or good AUC-value (>0.65) and for most also the %-change is substantial (>20%), and e) it appeared significant in different tests. About 15 lipids or lipid ratios, each with either a positive or negative CVD correlation, were selected based on the highest p-values and best sensitivity and specificity subjectively ensuring the balanced representation of all lipid classes. Sensitivity and specificity thresholds were annotated in cases where the threshold of 60 and 70 were reached, respectively.

Lipidomic analysis proved to be efficient in identifying novel plasma biomarkers for CVD complications.

Molecular lipid to molecular lipid ratio could be an important indicator of cellular lipid metabolism including e.g., enzyme activities in the lipid metabolism pathways. Thus, these ratios may provide more information as the absolute plasma concentrations of the molecular lipids alone. As the absolute molecular lipid plasma concentration differences in general between healthy individuals and atherosclerotic patients seem to be between 30-70%, it might be reasonable to calculate and use different ratios instead of absolute concentrations only. As lipoprotein particles (e.g. LDL, HDL, and VLDL) are serving as carriers for most of the lipids in the blood stream it is appropriate to relate molecular lipid concentrations to lipoprotein data. Thus, the molecular lipid to HDL-cholesterol, LDL-cholesterol, apolipoprotein A-I and apolipoprotein B ratios were calculated. In fact, a number of ratios between the concentrations of different molecular lipids outperformed absolute plasma concentrations as disease biomarkers in CVD patients.

As the detected lipids are carried in the lipoprotein particles (LDL, VLDL and HDL) it is obvious that the corresponding lipoprotein fraction concentrations will even improve the prediction potential of molecular lipids from the results of the present study in total serum/plasma samples.

The lipid lowering drug efficiency measurements have so far been based on LDL-C and HDL-C assays. As the inventors have herein observed more potential biomarkers that predict the development of high-risk CVD complications better than these classical analyses, future drug efficiency profiling should be based on new sensitive and specific biomarkers that are more directly related to the risk of severe CVD-related complications rather than to LDL-C.
